Would You Marry Your Husband's Brother?

You've been married to your husband for so many years. Unfortunately he died. It is the tradition of his family that in the event of his death, you're passed on to his senior brother if he has any or his junior brother if he has no senior brother. So what will you do? Choose to remain in your husbands family but this time as the wife of one of his brothers, who incidentally might also be married? Or take your kids and run?
